On the computer malware could steal any data/files/etc. which the user (i.e. your kid) has access too (ignoring UAC exploits).
As simple user he has limited options for "installing" new things. He has access only to the non-system partitions and only his user keys in registry.
The malware will run only when the kid is playing. It's bad, but it cannot damage what's important.
And in my case he will also have to get over the Internet Security's "Auto-Containment"
And on windows.. well.. it is not really hard to implement a keylogger.
I know, I've done a super-simple one in my 3rd year at Uni.
That was in MS-DOS/Win95. Now everything is much easier.
So, to get on-topic again, this also wouldn't have had him protected against this kind of malware.
I mean.. you could theoretically forbid applications to access the clipboard, but this also means you can't paste in them anymore.
I am no way saying that android is secure and windows is not.. however it is much easier to have your mobile clean than a windows computer.
But shared devices create new problems per se, whether smartphone, computer, tablet, etc.
That's correct. At least for clipboard hijacking user's double check is something easy to do and should become almost a reflex.
Bitsler has this implemented at withdraw - it asks the user double check a few parts of the address for sure. But for a wallet to do this.. I don't know, it could be annoying for many users.
